Calgary would take late picks / future considerations for sure.

Monahan (1.5M retained) + 4th for future considerations.

Calgary is going to really need that cap space and is entertaining a buyout, so I think you could get up to a 2nd (no retention). The guy was playing on the 4th line, and Calgary needs 20+M to sign just two players.

Given that Monahan played as a 4c this year, will be coming off a surgery for a bad injury, made gaudreau and tkachuk look bad, and that calgary desperately needs cap to resign their stars, I would not pay anything to take Monahan and would be looking for at least a second in return for the cap relief

All good suggestions so far. Monahan just seems like a hard guy to value right now, but I know Calgary desperately needs the cap space. That is if they don't send him to Robidas Island

Don't forget about what Fabbri and Vrana became after an Yzerman move. This would be a good deal for Detroit if they moved a 5th, 6th or 7th just for Monahan nothing retained. The risk vs reward for Detroit to "pay" for Monahan isnt so bad. The likely hood of a 5th, 6th, 7th round pick making it in the NHL is not very good. Calgary being in a spot that requires them to move his contract works for Detroit to gain more from Calgary. Id look for Calgary to maybe send back a 4th or 5th with Monahan, Detroit gives them future considerations... That would be a win. Overall though, like I said, worst case I would be ok with Yzerman giving up a 6th straight up. Its a one year deal, we have the room, experiment on this one.. say "but what if"... nothing to really lose

Just looking at the roster that is on this post, does Detroit need LHD? Are there enough pieces in the system that Wings fans are confident to fill the left side? Calgary has a ton of depth on LD and could easily package Valimaki to fill a hole in Detroit to make the deal more of a hockey trade than a cap move.
Monahan, Valimaki, Pick
Givani Smith, Pick

Left side is definitely a need right now, but also a need Detroit could fill via free agency (IE Jan Rutta). Edvinson will also be here next year and will be on the left side. He is reportedly as good if no better than Seider

Pretty much the way I see it. If he can get healthy and return to better form that he has been the last couple years, Yzerman looks like a genius. If he can't hack it anymore, at worst Detroit gave up a late pick who will probably never see the show. Very low risk from Detroit's side

monahan + a 3rd for a 7th

I have no problem rolling the dice on Monahan if the price is cheap. Apparently he's ahead of schedule after his hip surgery. 6'2 200 lbs 28 years old in October. 👍

Detroit also clearly needs depth at Center. And even if he only gets back to 75% of what he was, he's an upgrade over Suter

A healthy Monahan is an upgrade over Suter. I don't see the need to acquire Monahan unless we're getting a nice sweetener with it. We're in the middle of a rebuild. We're not going to make the playoffs with or without Monahan next season. We can just roll Larkin, Suter, Rasmussen and Veleno at C. There's no need to fast track things.

Unless its a Staal situation where Calgary is willing to send a pick to offload his deal. But I honestly can't tell if that's the case. Some think he's a bum, while others think he could return to form. At this point, he's a low risk lottery ticket
